I have found that with other appliances running, or a busy circuit, I have the same problem. Try to turn everything else in the house off and check again....A/C are often culprits. You can buy a line isolator for the plug, although they are just more money to spend. If this doesn't work, well, it could be a crappy home theaater receiver. It happens

In most surround sound systems the sub woofer is powered separately and uses a standard RCA coax connection to the receiver/amplifier.
Replacing is simply plugging in the new and reconnecting the coax cable.
Usually the audio signal is Dolby Digital 5.1 the (.1) is the LFE Sub-woofer. The connection is between the Subwoofer RCA connector on the amplifier and connects to the (LFE-Line) in on the subwoofer speaker.
Either the sub woofer speaker or the sub woofer amplifier section circuit has the fault. Contact any service technician to make diagnosis the faulty section. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/

Alright i had a chance to look over things, this is how you are going to hook up the sub. first we'll be connecting the surround sound unit to the sub woofer. surround sound unit sub woofer left front: positive (+) <-----to------------->(+) left speaker level in negative ( - )<- - -to- - - - - - ->( - ) left speaker level in
right front: positive (+) <-----to------------->(+) right speaker level in
negative ( - )<- - -to- - - - - - >( - ) right speaker level in
now that the surround sound unit is connected to the sub woofer you will need to connect the front surround sound speakers to the sub woofer. sub woofer front surround sound speaker left speaker level out (+)<-----to--------> (+) left front speaker left speaker level out( - ) <- - - to- - - - ->( - ) left front speaker
right speaker level out (+)<-----to--------> (+) right front speaker right speaker level out( - ) <- - - to- - - ->( - ) right front speaker
Alright now that the wires are all over the place and plugged in turn everything on and see how it sounds. let me know if everything is working as it should. if you need help with anything else or if something does not seem right please feel free to contact me via e-mail or phone Mark Woodring
no, u cant use the speakers with other normal DVD player because it wont have amplification for the speakers... u can use the sub to other dvd player because its inbuilt 120 watt woofer. ur dvd player is 5-disc player as wel as 120 X 2 and 80 X 3 watts amplifier (AV receiver ).... so just the JVC better sound thru the sub and speakers... ENJOY
